The 60V 40Ah lithium-ion battery is a high-capacity upgraded power configuration for mid-to-high-end Citycoco electric scooters, with standardized industrial dimensions and precise weight parameters that match most large-size Citycoco models. The overall external dimensions of the standard 60V 40Ah Citycoco battery are 380mm in length, 220mm in width, and 180mm in height. This size is optimized for the built-in battery compartment of mainstream 1500W–2000W Citycoco scooters, achieving a perfect fit without modification. Some detachable portable versions have slightly adjusted dimensions (375mm×215mm×175mm) through internal cell arrangement optimization, retaining compatibility with original car compartments while improving portability.

In terms of weight, the standard integrated 60V 40Ah Citycoco battery weighs approximately 22–24 kilograms. The weight difference mainly comes from different shell materials and BMS accessory configurations: metal fully sealed waterproof shells increase the weight by 1–2 kilograms, while plastic lightweight shells reduce the total weight appropriately. Compared with the traditional 60V 20Ah battery (12–14kg), the 40Ah model doubles the capacity with only a 70% weight increase, reflecting the high energy density advantage of ternary lithium cells used in Citycoco batteries. The internal structure adopts a multi-cell series-parallel combination design, with high-strength fixing brackets and shock-absorbing cotton between cells, ensuring that the battery maintains structural stability and no loose cell displacement during bumpy off-road driving.

The battery shell is made of high-hardness ABS waterproof and fireproof material, with a reserved charging port, power output port, and heat dissipation holes, which do not occupy extra installation space. The overall size design fully considers the heat dissipation demand of high-capacity discharge, avoiding performance attenuation caused by overheating during long-time high-power operation. The detachable 60V 40Ah battery version is designed with a portable handle and anti-slip lock structure, which is convenient for users to disassemble, carry, and charge indoors. In addition, the battery’s reserved wiring interface position and size are unified with the original factory standard, ensuring zero-difficulty replacement and upgrade for old Citycoco models. The precise size and weight design balance the vehicle’s center of gravity stability and cruising range performance, avoiding the problem of vehicle tilting or unstable driving caused by excessive battery weight.
